Trail Map

California State Highway 108 traverses over Sonora Pass in the Sierra Nevada mountain range at an elevation of 9,628 feet and is subject to winter closure at Highway 108 Sno-Park. Cross-country skiers and snowmobilers looking for a winter adventure begin their travels from Highway 108 Sno-Park.

Sno-Park permits are required for parking $5 a day, or $25 for a season pass. The Highway 108 Sno-Park has 62 parking stall for vehicles with trailers (37 are pull-through stalls). Sno-Park has a two vault toilets restroom and information boards. From Sno-Park, Kennedy Meadows is 18.5 miles one-way and is groomed on a regular basis during the winter months, conditions permitting.

The road/trail beyond Kennedy Meadows and up to Sonora Pass is NOT groomed. There are steep climbing slopes and narrow chutes beyond the Kennedy Meadows Road turnoff. Snowmachine operators will find several avalanche chutes near Chipmunk Flat, and portions beyond may be impassable to inexperienced snowmobilers. Ensure avalanche safety gear is carried at all times. For avalanche advisory information please visit the Sierra Avalanche Center website.

Please respect the Wilderness Areas on each side of Highway 108, and ride your machine on designated routes and in permitted areas. Maps are available at the Summit Ranger District Office or dowload a Geomarked PDF by clicking here: Over Snow Vehicle Use Map.
